I want to apply this, but user-space helpers got broken with this:
[Thu Oct 11 00:31:13 2012] (pid=12400) [ERROR] could not switch to namespace: Invalid argument
You can use conntrack-tools/doc/helper/conntrackd.conf as example.
You also need to use a Linux kernel 3.6 to test this user-space helper
feature, see: http://conntrack-tools.netfilter.org/manual.html#helpers
